One of the computers is MICRONCP, which is the one at 192.168.1.102. However the directory under MICRONCP is blank. I would have expected the Recordings subdirectory to show up there.
No it won't. You manually mounted //192.168.1.102/BKNET_V3/Recordings to appear at /media/Videos. The OSD GUI on the other hand should do as you expect, if it can connect successfully.
On your OSD, can you browse to Play|Browse -> Videos and navigate around your share okay?
I'm still unsure why you're having a problem. You're using the standard mount command that the OSD GUI uses too. Does the OSD detect your BKNET_V3/Recordings share correctly (Play|Browse -> network -> Search for Network -> MICRONCP -> Searching for Shared directories)?
Is it usual that a samba share has a name like "BKNET_V3/Recordings"? I usually thought they took the name only of the directory they are in, i.e. "Recordings"
Maybe that's where the OSD is getting confused?
